The MagLev turbine is a big step forward in the world of wind power. By using magnetism to levitate the blades friction is eliminated and more power can be produced without any additional power expense (since the magnetics require no energy to run). The MagLev has a low threshold velocity for producing energy, could theoretically survive for centuries and can power up to 750,000 homes. Though the initial investment involved hundreds of millions of dollars the payoff is potentially huge. .
In Germany, the largest wind-power producer, the government has been giving grants to builders of wind farms since the late 1980s, and requires utilities to buy electricity generated from renewable sources at premium rates. The extra cost is passed on to consumers.
Biomass refers to the conversion of plant matter into a transportation fuel (biofuel) or electricity (biopower ), usually by incinerating waste material or creating combustible gas through chemical processes. A significant amount of electricity also is made by gathering and burning landfill gas.
The world’s largest biomass power plant running exclusively on chicken manure has opened in the Netherlands. The power plant will deliver renewable electricity to 90,000 households. It has a capacity of 36.5 megawatts, and will generate more than 270 million kWh of electricity per year.
“ By practicing conservation tillage or planting grasses and trees, farmers and landowners are sequestering or holding carbon dioxide, and in turn, offsetting greenhouse gas emissions.”
At current market prices, a landowner can typically earn between $2 and $12 per acre per year depending upon the conservation practice. Landowners must sign a contract and commit to maintain the conservation practice through 2010
“ carbon credits,” which can then be sold on the Chicago Climate Exchange
A carbon tax is a tax on the carbon content of fuels — effectively a tax on the carbon dioxide emissions from burning fossil fuels (gas, oil, coal). Thus, carbon tax is shorthand for carbon dioxide tax or CO2 tax .
